IMPROVEMENT IN TOY WHISTLESi Specification forming part of LettersPatent No. 147,203, dated February 3, 1874; application filed August 13,1873.

To all whom it may concern: I

Be it known that I, HENRY J. Hum, of the city, county, and State of NewYork, have in-- vented a Toy, of which the following is a speci=fication: V

This toy consists of a screw-like wind-wheel combined with amouth-whistle in such manner that the wind issuing from the whistle willact on the wheel and cause it to rotate rapidly. The wheels by beingpainted in various ways may be made to produce very beautiful effects.

In the accompanying drawing, Figure l is a longitudinal section of thetoy and Fig. 2 is a transverse section of the same taken at theoutlet-orifices of the whistle, as indicated by the dotted line :20 x inFig. 1.

Similar lette s of reference indicate corresponding parts in bothfigures.

A indicates the whistle. It is taper in'form from its mouthpiece towardits opposite end,

where the wind-wheel is arranged. It has a cylindrical air-passage, (1,extending along it from the mouthpiece, and two orifices, b b, throughwhich the air issues from the passage. These orifices are formed in theordinary way by cutting notches in the sides of the whistlestock in suchmanner that sharp edges are presented to the escaping air, and the outerinclined planes forming these sharp edges are made at such angle as todirect the issuing air to the wheel. The plug 0 of the whistle islocated in the passage ajust in rear of the issue-orifices, as usual.The wind-wheel B is made of sheet metal, paper, or other material, andresembles greatly a screw-propeller as it has numerouslaterally-inclined arms or blades. It may he painted in various ways soas to produce pleasant effects when rotating. It is arranged loosely ona pin, e, which is inserted into the end of the whistle. The taper formof the whistle enables the air which issues from it to have free accessto the wheel to rotate it.

\Vhat I claim as my invention is The whistle A, provided with thecylindrical air-passage a and the orifices b, formed with inclined sidesso as to direct the air against the blades of the wheel B, as hereinshown and described.
